Can I just make a short clarification? Except in really serious circumstances, when [i:3k77bh4q]economia[/i:3k77bh4q] may be applied (like the person is on the point of death and cannot get to an appropriate priest), Roman Catholics may not partake of the Orthodox Eucharist and vice versa. If we were to allow this we would effectively be saying that we are in communion with Rome when we are not. In Orthodox ecclesiology unity is only ever Eucharistic unity.
I, personally, totally agree with this position (as Scott knows – we’ve debated it elsewhere) and would not change it. I can’t see why Roman Catholics would wish to change their position either as, Papal primacy aside, our two churches’ ecclesiologies are not that different. I hope that my non-RC views are not unwelcome here.
